Working with the elderly in Germany

Young people always try to avoid the contact with everything is old.
The word itself has acquired a negative connotation.
If you're tired, and you don't wanna go out, you're too old.
If music is too loud, you're too old.
If your outfit is too “vintage”, you're too old.
When I tell someone that I'm working with the elderly, the answer often is :" With older people?! Why?"
Well, thanks to my project, for example, I've learned so many things about what happened in Germany during and after the Second World War.
Frau B. came from Poland during the Thirties, and she uses to ask me if I’m polish too, because she misses speaking in her mother tongue.
Herr N. can speak English very well. After the war, young german guys were sent to USA “to learn democracy”.
Frau S. lived in East Berlin. She wasn’t allowed to choose her job, and escaped two months before the wall fell down. She took the S-bahn with a friend and no money in her pocket.
They told me that the U-bahn from Friedrichstraße to Hallesches Tor was dark, that the German reunification was a disaster for all the people from the eastern part who lost the job.
During these five months, I understood that behind every name, behind every face and every behavior, there is a story, a past, which is always related to the history of a country.
